The 3.48 Ga Dresser formation hosts microfossils of prokaryotic filaments in silica veins, the earliest fossil evidence of life on Earth, [70] but their origins may be volcanic. [ 71 ] 3.465-billion-year-old Australian Apex chert rocks may once have contained microorganisms , [ 72 ] [ 5 ] although the validity of these findings has been contested.
The earliest known remains of Cro-Magnon-like humans are radiocarbon dated to 43,000–46,000 BP, found in Bulgaria, Italy, and Great Britain. [33] [34] Europe: Bulgaria: 46-44: Bacho Kiro cave: A tooth and six bone fragments are the earliest modern human remains yet found in Europe. [35] Europe: Italy: 45–44: Grotta del Cavallo, Apulia
After 1.5 million years ago (extinction of Paranthropus), all fossils shown are human (genus Homo). After 11,500 years ago (11.5 ka, beginning of the Holocene), all fossils shown are Homo sapiens (anatomically modern humans), illustrating recent divergence in the formation of modern human sub-populations.
Life on Earth may have begun even earlier than biologists suspected, at a time when the solar system was still in its infancy. Earth's oldest fossils yet discovered, give hope for life on Mars ...
The earliest evidence for life on Earth includes: 3.8 billion-year-old biogenic hematite in a banded iron formation of the Nuvvuagittuq Greenstone Belt in Canada; [30] graphite in 3.7 billion-year-old metasedimentary rocks in western Greenland; [31] and microbial mat fossils in 3.48 billion-year-old sandstone in Western Australia.
A 1.4-million-year-old fossil jaw discovered in a South African cave in 1949 has now been identified as that of a previously unknown human relative species dubbed the “nutcracker man ...
The footprints, found at several sites in southern Africa, were recently identified as the oldest birdlike tracks ever found, preceding the earliest known skeletal fossils of avians by about 60 ...
